Name :
Recombinant Canine IL-17A Protein
Biological Activity :
Background :
IL17, also known as IL17a, is a cytokine that belongs to the IL-17 family. Cytokines are proteinaceous signaling compounds that are major mediators of the immune response. They control many different cellular functions including proliferation, differentiation, and cell survival/apoptosis but are also involved in several pathophysiological processes including viral infections and autoimmune diseases. Cytokines are synthesized under various stimuli by a variety of cells of both the innate (monocytes, macrophages, dendritic cells) and adaptive (T- and B-cells) immune systems. The IL-17 family of cytokines includes six members, IL-17/IL-17A, IL-17B, IL-17C, IL-17D, IL-17E/IL-25, and IL-17F, which are produced by multiple cell types. IL-17 regulates the activities of NF-kappaB and mitogen-activated protein kinases. This cytokine can stimulate the expression of IL6 and cyclooxygenase-2 (PTGS2/COX-2), as well as enhance the production of nitric oxide (NO). High levels of IL-17 are associated with several chronic inflammatory diseases including rheumatoid arthritis, psoriasis, and multiple sclerosis.

Biological Activity :
1. Measured by its binding ability in a functional ELISA. Immobilized Canine IL17A (cat: 70102-DNAE) at 10 μg/ml (100 μl/well) can bind human IL17Ra (Cat:10895-H03H), The EC50 of human IL17Ra (Cat:10895-H03H) is 6.0-15.0 ng/ml.2. Measured by its ability to induce IL-6 secretion by HFF human foreskin fibroblast cells. The ED50 for this effect is typically 1-5 ng/mL.
